Remember this advice isn't official. There is no guarantee it will reflect your experience because university applications can change between years. Check the official Cambridge and Oxford websites for more accurate information on this year's application format and the required tests.
Also, someone else's experience may not reflect your own. Most interviews are more like conversations than tests and like, any conversation, they are quite interactive.
I arrived the night before and was shown to my room by a current student. The next day I went straight to my first interview with two
The first interview was mainly problem solving. I was asked about my thoughts on a list of expensive drugs the NHS uses and then about advances in medicine. I then had to interpret a certain type of scan.
The second interview was more chemistry and biology focussed. I was asked about the periodic table which then formed the basis of a number of follow-up questions, including about DNA and tRNA, for example. I was then asked about drug delivery.
Reading books which covered some basic medical science beyond A-Level. Also talking through problems with friends or family and showing them my thought processes.
I thought my interviews had gone really badly because I often got things wrong but because I had explained how I got to that conclusion the fellows were able to see where I’d gone wrong and point me in the right direction. I think it’s good to explain your thoughts as you go to the interviewers.
